Check Digit Verification of cas no

The CAS Registry Mumber 42397-30-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,3,9 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42397-30:
(7*4)+(6*2)+(5*3)+(4*9)+(3*7)+(2*3)+(1*0)=118
118 % 10 = 8
So 42397-30-8 is a valid CAS Registry Number.

Organocatalytic Michael addition/intramolecular Julia-Kocienski olefination for the preparation of nitrocyclohexenes

Rodrigo, Eduardo,Garcia Ruano, Jose Luis,Cid, M. Belen

, p. 10737 - 10746 (2013/11/19)

An asymmetric organocatalytic [3 + 3] annulation strategy based on a Michael addition/intramolecular Julia-Kocienski olefination sequence has been developed for the synthesis of 4-substituted-5-nitrocyclohex-1-ene compounds. The strategy is an alternative to the direct reluctant enantioselective Diels-Alder approach. The potential of the methodology has been demonstrated with a concise enantioselective formal synthesis of trandolapril.
